Abstract
Purpose: This study aimed to investigate the most prescribed medications and principle diagnoses for category D and X drugs during pregnancy using a population-based dataset in Taiwan. Methods: The data for the present study were sourced from the Taiwan Longitudinal Health Insurance Database 2000. We selected 14125 women who had live singleton births between 1 January 2009 and 31 December 2011. In total, 217226 prescriptions prescribed to these pregnant women were identified. Results: Of the total 217226 prescriptions, 1.1% were category D or X drugs; in the first, second, and third trimesters of pregnancy, 1.8%, 0.7%, and 0.5% of prescriptions were category D or X drugs, respectively. Progestins (15.3%) and propylthiouracil (10.7%) were the two most frequently prescribed category D or X drugs during pregnancy. In particular, progestins (20.4%) and estrogens (15.6%) were the most frequently prescribed category D or X drug in the first trimester of pregnancy. Propylthiouracil was the most prescribed category D or X drug in the second (20.3%) and third trimesters (23.1%) of pregnancy, respectively. The most common principal diagnosis during pregnancy was "disorders of menstruation and other abnormal bleeding from the female genital tract" (22% of all principal diagnoses for prescribing category D and X drugs). Conclusions: Our study found that the physicians obviously reduced the use of category D and X drugs for women after becoming aware that they were pregnant. Copyright
